Title: Harmonic mixer
Inventor: GIDOU TAKANOBU
IPC: H03D9/06
Filed: 1996-09-02
Abstract: PROBLEM TO BE SOLVED: To make a mixer small in size and to avoid deterioration in the characteristic of the mixer by eliminating electromagnetic coupling of a short/ open stub. SOLUTION: A 3-layer printed circuit board 1 is employed. A solid earth layer is formed as a 2nd layer, a local oscillation signal introduction section 3 and a short stub 5 are formed as the 1st layer, and an RF signal output section 4 and an open stub 6 are formed as a 3rd layer. Thus, since the coupling between the two stubs 5, 6 is eliminated and the two stubs 5, 6 are arranged in the same direction with respect to a signal line, the occupied area of the mixer section on the printed circuit board is reduced.

Title: Correction method of air-fuel ratio and correction device for the same
Inventor: MANAKA TOSHIO
IPC: F02D41/04
Filed: 1988-09-19
Abstract: PURPOSE:To enable the satisfactory compensation of air-fuel ratio in a transition period without increasing the load and memory capacity of CPU by conducting an estimating calculation of the fuel amount adhered to a wall face and an estimating calculation for calculating a correction factor which is a multiplier to a basic injection quantity based on the estimating calculation according to independent particular schemes. CONSTITUTION:The fuel feed amount in a transition period is corrected by a transition correction factor K1 obtained by a scheme I, wherein the adhesion of the fuel to an inlet air passage wall face is X, the evaporation time constant of the adhered fuel is tau, and the ratio of the fuel adhered amount to the fuel feed amount in a steady running is beta<1>. According to this method, the calculation of a fuel injection quantity and the calculation of the fuel amount adhered to the wall face are independently conducted, and then the fuel injection quantity is corrected by the above fuel amount adhered to the wall face (estimated value). Thus, the air/fuel ratio in the transition period can be maintained at a desired value without increasing the load and memory capacity of a CPU.

Filed: 1988-09-16
Abstract: PURPOSE:To hold normal video display performance even when input electric field strength is increased by providing an RF.AGC switching means to quicken the start point of an RF.AGC for tuner when the input electric field strength goes over a certain level. CONSTITUTION:Only an IF.AGC loop is operated when the input electric field strength is set between levels (A-B), and when the input electric field strength exceeds the level B, the operation of an RF.AGC loop is started. When the input electric field strength arrives at a level D, the voltage at both ends of the capacitor 10 become higher a reference voltage, and an RF.AGC start point switching circuit 15 is operated. As a result, an input voltage at a resistor 11 to an RF.AGC circuit 3d is increased from a preset voltage to a voltage Vcc, and the damping quantity (b) of the RF.AGC is increased, and the damping quantity (a) of the IF.AGC loop is decreased. In such a way, since the range of the input electric field strength where the AGC is operated normally can be taken widely, consistency between the improvement of a video S/N and the video display performance when strong input is applied can be attained.

Title: Alkaline battery and negative electrode active material therefor
Inventor: NAKAMURA KIYONOBU
IPC: H01M4/06
Filed: 1988-09-20
Abstract: PURPOSE:To greatly suppress hydrogen gas generation and yet improve discharge performance by adding a particular amount of polyoxyethylene alkylether phosphoric ester to a negative electrode active material consisting of zinc alloy powder. CONSTITUTION:There are comprised zinc alloy powder, an electrolyte, and a negative electrode material 3 consisting of 100 weight parts of zinc alloy powdery and 0.001-5.0 pts.wt. of polyoxyethylene alkylether phosphoric ester added to it. If the added amount of polyoxyethylene alkylether phosphoric ester is less than 0.001 pts.wt., the effect to improve corrosion resistance of zinc and prevent hydrogen generation can not be obtained. On the other hand, if the amount is more than 5.0 pts.wt., good discharge performance can not be obtained because a barrier is formed by the polyoxyethylene alkylether phosphoric ester to prevent the dissolving reaction of zinc, etc. Thus, hydrogen gas generation in the battery is greatly suppressed and yet the battery performance is improved even if the mercury content ratio is lowered than heretofore.
